Tron: Legacy may not have been a hit of Pirates of the Caribbean-sized proportions for Disney, but they're persisting with the homegrown franchise. Tron 3 is still in development, and has just hired a new writer to continue cracking the code. The Hollywood Reporter reports that Disney has hired writer Jesse Wigutow to take over scripting duties, and that Legacy director Joseph Kosinski is attached to helm the film. Wigutow doesn't have many produced credits to his name, but has been tasked with penning Disney's Peter Pan fantasy Peter and the Starcatchers, and with adapting Robert Lundlam's The Osterman Weekend. Hollywood.com has reached out to Disney, who could not immediately be reached for comment.
